North America's Great Lakes Ice at Historic Low | NOAA

North America's Great Lakes Ice at Historic Low | NOAA


For the second consecutive year, ice cover on the Great Lakes remains significantly below average for this time of year. Typically, peak ice cover at levels are around 53 percent. As of February 11, 2024, total ice coverage across all lakes measured a mere 2.7 percent. Lakes Erie and Ontario are basically at—or tied with—their respective historic lows for this time of year, making both essentially ice-free. This record low ice cover is largely attributed to unusually warm temperatures throughout the region in December 2023, paired with the generally short duration of Arctic air blasts.

The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the east-central interior of North America that connect to the Atlantic Ocean via the Saint Lawrence River. The five lakes are Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border.

NASA Remembers Astronaut Richard Truly

NASA Remembers Astronaut Richard Truly

"We're saddened by the passing of Astronaut Richard Truly at the age of 86."

In 1965, Truly became one of the first military astronauts selected to the Air Force’s Manned Orbiting Laboratory program and transferred to NASA as an astronaut in August 1969. He served as capsule communicator for all three Skylab missions in 1973 and the Apollo-Soyuz mission in 1975. He was pilot for one of the two-astronaut crews that flew the 747/Space Shuttle Enterprise approach and landing test flights during 1977. He then was backup pilot for STS-1, the first orbital test of the Shuttle. His first space flight was as pilot of Space Shuttle Columbia (STS-2), significant as the first piloted spacecraft to be reflown in space. His second flight (STS-8) was as commander of Space Shuttle Challenger, the first night launch and landing in the Shuttle program.

The former Shuttle astronaut served as the first commander of the Naval Space Command in Dahlgren, Virginia, established Oct. 1, 1983.

Vice Admiral Richard H. Truly returned to NASA to become NASA’s Associate Administrator for Space Flight on February 20, 1986. In this position, he led the painstaking rebuilding of the Space Shuttle program. This was highlighted by NASA’s celebrated “return to flight” on September 29, 1988, when Discovery lifted off from Kennedy Space Center, Florida, on the first Shuttle mission in almost 3 years.

He served as NASA’s eighth Administrator from February 1989 to 1992.

New Link Found Between Water and Planet Formation | ESO

New Link Found Between Water and Planet Formation | ESO

Researchers have found water vapor in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in planet formation. Yet, until now, we had never been able to map how water is distributed in a stable, cool disc—the type of disc that offers the most favorable conditions for planets to form around stars. The new findings were made possible thanks to the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. This video summarizes the discovery.

Three Moon Surface Images Released | Intuitive Machines Odysseus Lunar Lander

Three Moon Surface Images Released Intuitive Machines Odysseus Lunar Lander
"Taken on February 27th, flight controllers commanded Odysseus to capture a new image using its narrow-field-of-view camera. Previous attempts to send photos from landing and the days following returned unusable imagery. After successfully transmitting the image to Earth, flight controllers received additional insight into Odysseus' position on the lunar surface."
"This image illustrates Odysseus' landing strut performing its primary task, absorbing first contact with the lunar surface to preserve mission integrity."

"The IM-1 Mission successfully landed the first spacecraft on the Moon's south pole region, marking the United States' first return since Apollo 17 and the first commercial lunar lander to transmit valuable science data of each NASA payload from the lunar surface . . ."
On February 28, 2024, Intuitive Machines provided an update on the status of the Odysseus Lunar Lander located near the Malapert A crater in the Moon’s South Pole region. They released three new images of the moon's surface from the landing area.

On February 22, 2024, the IM-1 Mission Nova-C Moon Lander, named "Odysseus," became the first American spacecraft to land on the Moon’s surface since the NASA Apollo 17 moon landing in 1972.

Dwarf Galaxies Reionized the Universe: Galaxy Cluster Abell 2744 | Webb Telescope

Dwarf Galaxies Reionized the Universe: Galaxy Cluster Abell 2744 | Webb Telescope


Using the unprecedented capabilities of the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope, an international team of scientists have obtained the first spectroscopic observations of the faintest galaxies during the first billion years of the Universe. These findings help answer a longstanding question for astronomers: what sources caused the reionization of the Universe? These news results have effectively demonstrated that small dwarf galaxies are the likely producers of prodigious amounts of energetic radiation.

Researching the evolution of the early Universe is an important aspect of modern astronomy. Much remains to be understood about the time in the Universe’s early history known as the era of reionization. It was a period of darkness without any stars or galaxies, filled with a dense fog of hydrogen gas, until the first stars ionized the gas around them and light began to travel through. Astronomers have spent decades trying to identify the sources that emitted radiation powerful enough to gradually clear away this hydrogen fog that blanketed the early Universe.

“This discovery unveils the crucial role played by ultra-faint galaxies in the early Universe's evolution,” said team member Iryna Chemerynska of the Institut d’Astrophysique de Paris in France. “They produce ionizing photons that transform neutral hydrogen into ionized plasma during cosmic reionization. It highlights the importance of understanding low-mass galaxies in shaping the Universe's history.”

“These cosmic powerhouses collectively emit more than enough energy to get the job done,” added team leader Hakim Atek, Institut d’Astrophysique de Paris, CNRS, Sorbonne Université, France, and lead author of the paper describing this result. “Despite their tiny size, these low-mass galaxies are prolific producers of energetic radiation, and their abundance during this period is so substantial that their collective influence can transform the entire state of the Universe.”

Astronomers estimate 50,000 sources of near-infrared light are represented in this image from the James Webb Space Telescope. Their light has travelled through various distances to reach the telescope’s detectors, representing the vastness of space in a single image. A foreground star in our own galaxy, to the right of the image center, displays Webb’s distinctive diffraction spikes. Bright white sources surrounded by a hazy glow are the galaxies of Pandora’s Cluster, a conglomeration of already-massive clusters of galaxies coming together to form a mega cluster. The concentration of mass is so great that the fabric of spacetime is warped by gravity, creating a natural, super-magnifying glass called a 'gravitational lens' that astronomers can use to see very distant sources of light beyond the cluster that would otherwise be undetectable, even to Webb.

These lensed sources appear red in the image, and often as elongated arcs distorted by the gravitational lens. Many of these are galaxies from the early Universe, with their contents magnified and stretched out for astronomers to study. 

Image Description: A crowded galaxy field on a black background, with one large star dominating the image just right of center. Three areas are concentrated with larger white hazy blobs on the left, lower right, and upper right above the single star. Scattered between these areas are many smaller sources of light; some also have a hazy white glow, while many other are red or orange.

These results have been published today in the journal Nature:

Listen to the Universe: New NASA Sonifications & Documentary | NASA Chandra

Listen to the Universe: New NASA Sonifications & Documentary | NASA Chandra

Three new sonifications of images from NASA’s Chandra X-ray Observatory and other telescopes have been released. Sonification is the process of translating data into sounds. In the case of Chandra and other telescopes, scientific data are collected from space as digital signals that are commonly turned into visual imagery. The sonification project takes these data through another step of mapping the information into sound.

The three new sonifications feature different objects observed by NASA telescopes. 

1) IC 443 is a supernova remnant, or the debris of an exploded star, which astronomers have nicknamed the Jellyfish Nebula. A visual composite image of IC 443 includes X-rays from NASA’s Chandra X-ray Observatory, and the German ROSAT X-ray telescope, along with radio data from the NSF’s Very Large Array, and optical data from the Digitized Sky Survey. The sounds in the sonification of IC 443 sounds are mapped to colors in the image with red colors heard as lower pitches, green as medium pitches, and the blue light as the higher pitches. This creates notes that sweep up and down in pitch continuously. The background stars in the optical image have been converted to water drop sounds in the sonification. 

2) Messier 74 is a spiral galaxy like our Milky Way. It is seen face-on from Earth’s vantage point some 32 million light-years away. In the image, X-rays from Chandra have been combined with an infrared view of M74 from NASA’s James Webb Space Telescope as well as optical data from NASA’s Hubble Space Telescope. In sonifying these data, the Chandra sources correspond to relatively high musical pitches of glassy, ethereal clear plucked sounds. The Webb data are represented by low, medium, and high frequency ranges of pitches respectively and the brightest stars are percussive sounds. The Hubble data have been turned into breathy synthesizer sounds, along with thin, metallic plucked sounds for bright stars and clusters.

3) The third new sonification is of MSH 15-52, a cloud of energized particles blown away from a dead, collapsed star. This image includes X-rays from the Imaging X-ray Polarimetry Explorer, or IXPE, as well as Chandra. These data have been combined with infrared data from the Dark Energy Plane Survey 2. In sound, the scan goes from the bottom to the top. The brightness of the Chandra data of the cloud have been converted into rough string-like sounds. The blast wave is represented by a range of pitches of firework-type noises. The IXPE data are heard as wind-like sounds. The infrared data are mapped to musical pitches of a synthesizer sound.

India's Space Agency Announces Four Astronauts for First Spaceflight Mission

India's Space Agency Announces Four Astronauts for First Spaceflight Mission

India's Prime Minister Narendra Modi revealed the names of four astronauts selected for the country's first crewed mission to low-Earth orbit—the Gaganyaan Mission. Gaganyaan means "sky craft" in Hindi. The mission involves the launch of a crewed spacecraft over the next year to an orbit of 400 kilometers with a return landing in the Indian Ocean. Prime Minister Modi awarded the four crew members—all of them air force officers—"astronaut wings" at a space center in Thiruvananthapuram in Kerala state on Tuesday, Feb. 27, 2024, during their first public appearance after months of rigorous training. The four astronauts undergoing training for India's human spaceflight mission are: 

• Group Captain Prashanth BalaKrishnan Nair

• Group Captain Ajit Krishnan

• Group Captain Angad Prathap

• Wing Commander Shubhansku Shukla

Wing Commander Rakesh Sharma, a former Indian Air Force pilot, flew aboard the Soyuz T-11 spacecraft on April 3, 1984, for the sixth expedition to the Soviet Salyut 7 space station. This was part of the Soviet Interkosmos program. To date, Sharma is the only Indian citizen to travel in space.

Only the United States, Russia, and China have sent their own crewed missions into space. Astronauts from more than three dozen other countries have made space trips aboard either U.S. or Russian missions.
